'Whereof' in the Bible

This Jesus hath God raised up, whereof we all are witnesses.

And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses.

whom the heaven must receive until the times of restoration of all things, whereof God spake by the mouth of His holy prophets that have been from of old.

And they took him, and brought him unto Areopagus, saying, May we know what this new doctrine, whereof thou speakest, is?

Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.

Them take, and purify thyself with them, and be at charges with them, that they may shave their heads: and all may know that those things, whereof they were informed concerning thee, are nothing; but that thou thyself also walkest orderly, and keepest the law.

Commanding his accusers to come unto thee: by examining of whom thyself mayest take knowledge of all these things, whereof we accuse him.

Neither can they prove the things whereof they now accuse me.

For if I be an offender, or have committed any thing worthy of death, I refuse not to die: but if there be none of these things whereof these accuse me, no man may deliver me unto them. I appeal unto Caesar.

I think myself happy, king Agrippa, because I shall answer for myself this day before thee touching all the things whereof I am accused of the Jews:

But when the Jews spake against it, I was constrained to appeal unto Caesar; not that I had aught whereof to accuse my nation.
